The authors would like to make the following corrections to this paper [1]: In the original article, the captions of Figures 2–4 are not matched with the figures. The caption of Figure 2 was wrongly used for Figure 3, the caption of Figure 3 was wrongly used for Figure 4, and the caption of Figure 4 was wrongly used for Figure 2. The correct captions with the figures appear below. Figure 2. Clinopyroxene variability indicative of Stage A crystallization.

Abstract

The authors would like to make the following corrections to this paper [1]: In the original article, the captions of Figures 2–4 are not matched with the figures. The caption of Figure 2 was wrongly used for Figure 3, the caption of Figure 3 was wrongly used for Figure 4, and the caption of Figure 4 was wrongly used for Figure 2. The correct captions with the figures appear below. Figure 2. Clinopyroxene variability indicative of Stage A crystallization. (a) TiO2 (wt%) versus Mg# for the clinopyroxene crystals in basalts to basaltic andesite lavas, top to bottom: D5; D1 and D6; MRS2 and D4. Estimated analytical error (2 standard deviation) was smaller than symbol size. The yellow box and the yellow vertical band refer to the Mg# equilibrium values indicated by the PX-MELTS [18] and the PX-08 (this study) results, respectively. Analyses of selected crystals (single or in glomerocrysts) are indicated with their abbreviation (see Supplementary Tables S2–S13) and marked with coloured arrows connecting core to rim or enclosed within dashed lines. The D5 clinopyroxene field is reported in green. Photomicrographs under parallel nicols are reported for some crystals (location of the analysed transects or points marked by red lines or dots, respectively); further photomicrographs are reported in Supporting Materials (Figure S1). Mineral abbreviations: Ol = olivine; Cpx = clinopyroxene; Pl = plagioclase; Glomerocrysts = GLOM. The Mg#-TiO2 trend exhibited by these cargoes identifies “Stage A” cooling and crystallization during melt percolation at the pre-eruptive storage zone at the base of the MV crust, outlined in (b). Black lines enclose clinopyroxene compositions found at island-arc settings, recording growth in deep crustal mush environments: basic lavas from Stromboli [37] and Ruapehu [36]; exhumed island arc crustal section [35].

Boxes “Stage B” and “Stage C” mark the location of the crystallization events recorded by the clinopyroxene cargoes of the D2 basaltic andesite and the andesite lavas, respectively. Figure 4.
